Does anyone have <a href="http://www.skymall.com/webapp/skystore?process=prodDisplay&action=&pid=101887706&catId=Search" target="_blank">this?</a> We're planning a trip to England and I just can't imagine holding him in my lap for the entire flight? (does that make me a bad mom???) But then if I have to have a car seat for him I thought this which can be wheeled might be convenient. But is it worth it? Is it safe? Any knowledge would be appreciated. Thanks!!!
